The VIP entrance leading from the Queen Elizabeth II Pier on the river Thames to the O2 has been given the LED lighting treatment to improve the visitor experience.
Architen Landrell have helped shape this striking part of the venue thanks to their design, manufacture and installation of a weatherproof tunnel leading visitors to the Arena from the waterfront.
35 Tryka Module 36 IP67 with oval optics are installed inside the custom-built 150m long tunnel, with Tryka's IDS-4 rack Intelligent Drive System controlled by an LPC DMX system.
The luminaires offer a wide beam angle for illuminating the vast area and their IP rating means they are ideal for exterior use and their units are installed on a prominent position on the columns and therefore needed To be aesthetically pleasing.
Rowell continues: "A further achievement was installing all the drivers in a control room 150m away from the luminaires, which resulted in an impressive number of cable routes which had to be hidden in the supporting steel work."

Piezoelectric Elements For Inkjet Piezo Transducer
Piezoelectric ceramic ring
Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
